The proposed approach, namely Subspace Support Vector Data\nDescription, maps the data to a subspace that is optimized for one-class\nclassification. In that feature space, the optimal hypersphere enclosing the\ntarget class is then determined. The method iteratively optimizes the data\nmapping along with data description in order to define a compact class\nrepresentation in a low-dimensional feature space. We provide both linear and\nnon-linear mappings for the proposed method. Experiments on 14 publicly\navailable datasets indicate that the proposed Subspace Support Vector Data\nDescription provides better performance compared to baselines and other\nrecently proposed one-class classification methods.","url_abs":"http://arxiv.org/abs/1802.03989v3","url_pdf":"http://arxiv.org/pdf/1802.03989v3.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"subspace-support-vector-data-description","repo_url":"https://github.com/fahadsohrab/ssvdd","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":{"status":"unanswered"}}],"tasks":[{"task_slug":"classification-1","task_name":"Classification"},{"task_slug":"classification","task_name":"General Classification"},{"task_slug":"one-class-classification","task_name":"One-Class Classification"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1802.03989","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
